Application filed June 19,

To all 10 hom it may concern:

Be it known that I, IVILLIAM L. BARRETT, a citizen of the United States of America, and a resident of Waterloo, Blackhawk county, Iowa, have invented certain new and useful Improvements in HandCultivators, of which the following is a specification.

My invention relates to improvements in hand Cultivators, and the object of my improvement is to supply a tool-carrying hand cultivator with means for adjusting the relative positions of the tools both vertically and laterally, as also to permit interchange thereof with other tools. This object I have attained by the means which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Figure 1 is a sideelevation, and Fig. 2 a plan view of my improved hand cultivator, in both a part of the handle being broken away. Fig. 3 is.

a plan view of a modification of said device.

Similar numerals of reference denote similar parts throughout the several views.

The numeral 1 denotes an elongated handle on one end of which is fixed a socket 2 provided with an alined projection 3, the

latter preferably discoidal, centrally transversely orificed, and provided on one side face with numerous radially-disposed detents. Upon this projection or clutch-member is fitted a mating clutch-member 4, whose like radial teeth 5 fit between and engage the detents on the member 3, and this member 4 has a registering central or fice, a bolt 6 traversing the said orifices, and a wing-nut 7 securing said members together in such a relative relation that the member 4 is adjusted on the member 3 as desired.-

The member 4 has a forwardly directed integral projection formed into a receivinghead 8, the latter being elongated transversely and being hollowed longitudinally to receive the middle bar or portion of an elastic forked, member 10, the forks whereof serve as supporting shanks for tools such as blades 12 secured removably on the downwardly curved extremities thereof. These shanks may be partially twisted at 11 to have inwardly-directed parts which stiffen them. The forked body 10 has its medial part which is seated in the hollow of the head 8 secured thereto by means of bolts 9.

Specification of Letters Patent.-

Patented Mar. @1921. 1920. Serial No. 390,200. l

As the forks of the body 10 are resilient,

the tools 12 may be adjusted laterally to and from each other by the following-described adjustableconnecting-means. In each web I 11 is an orlfice 14: receiving the hooked outer end of a threadedrod-part 15, the parts 15 being alined and their opposed threaded ends joined adjustably by means of a turnbuckle 16; The forks l0 willelastically yield sufficiently to permit .this adjustment, while the forks may have their angle of inclination changed by use" of the above-mentioned 7 adjustable clutch-members 3 and 4.. Thetools or blades 12 are secured to the forks by bolts 13, so these tools may be removed arlid other or different tools mounted in their p ace,

In Fig. 3, the clutch-members 3-4: are the same,'but thehead 17 of the projection 8 is solid, and longer, and has at each end forks 18. Tool-carrying shanks 10 are inserted between these end forks, and secured thereto removably by means of bolts 19. Inthis modification the shanks are rigid, and the adjustment by only vertically rocking the member 4 relatively to the member 3'.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is:

1. In a device of the character described,

a handle, a clutch-face member rigidlymounted thereon, soil-working implements, and elastic connecting supporting elements between said implements and said member adjustably secured on the latter for vertical rocking adjustments.

2. In a device of the character-described, a handle, laterally spaced soil-working implements, and a U-shaped supporting device on whose extremities the implements are mounted, the device being mounted for ver- 7 tical rocking adjustments o'nsaid handle, and the members of the device being elastic, and laterally-adjustable connections between said members.

3. In a'device of the character described, a handle, a shank mounted thereon for vertical rocking adjustments, laterally adjustable elastic tool-carrying members mounted on said shank, and tools mounted removably on said members. f

4. In a device of the character described,

a handle, a branched body with-elastic members spaced apart laterally, soil-Working tools mounted terminally on said members members having stifiening-means for ren- 10 clering them non-elastic vertically only, and adjustable connecting-means between said members, comprising elements connected to the members transversely and a turn-buckle connecting said elements.
